I wrote a few poems not sure they qualify for that somewhat esoteric title. Each time I did this, it was done expressing some emotion such as losing my grandson or deep love for my wife etc. Also when I was diagnosed with MDR TB. I don't claim they were "arty" but they did give me a sense of release and today I can go back and re-read them with some "revision" of those erstwhile emotions

I dabbled some as well a long time ago. Helped me deal with depression quite well actually, I lived.

EDIT: Reg that poem, I will recount some "wisdom" I encountered years ago: "Bitches aint nuthin but tricks and hoes."

FWIW: In std. 2 a teacher marked my essay down with: "Children of your age shouldn't write like this". I thought this was a definite mixed message, and still think the teacher was being a bit of a retard.

Same principle applies as why a banknote is worth anything: there is a limited supply and there is general agreement that it has value. Ain't got anything to do with the aesthetics, whatever the learned art professors might tell you after the fact.

I got this question (i.e. why this sort of art sells for so much) on Quora so often I eventually wrote a whole blog post about it, but I'd have to go look it up now. Will post the link here if and when I find it.
